Hello,I have been checking the universal soldering controller and Arhi SID projects for some times now, and I have just two questions:1- Why bother making such controllers when you can just buy an AOYUE int936 for only 37€ and you can use all hakko clones tips and heater elements. This AOYUE seems to be the true clone of the original HAKKO 936.http://www.wiltec.de/aoyue-soudure-stat ... r-cms.html
